Are you battling persistent and frustrating electrical issues in your Chevrolet Avalanche 2500 or other GM truck? Symptoms like malfunctioning power windows, a dead HVAC system, erratic lights, or a security system that prevents your truck from starting often point to a single culprit: a failing Body Control Module (BCM). This essential component is the central command center for your vehicle’s body electronics. When it fails, it can cause a cascade of problems that are difficult to diagnose. Restore full functionality and reliability with our expertly programmed BCM, a direct-fit solution for part number 15137395.
Why Choose Our Programmed 2002-2006 Avalanche 2500 BCM?
This isn’t just a replacement part; it’s a complete, ready-to-install solution. Each module is pre-programmed to your vehicle’s specific VIN, ensuring it works seamlessly with your existing systems right out of the box. This eliminates the need for an expensive trip to the dealership for programming. Built to strict OEM standards, this module ensures dependable performance and longevity, putting an end to your electrical gremlins.
Common Symptoms of a Failing BCM:
- ✔ Loss of HVAC controls or an A/C blower that works only on some speeds or not at all.
- ✔ An illuminated airbag warning light, often with diagnostic trouble codes (DTCs) like B1001.
- ✔ Power windows, door locks, or interior/exterior lights that operate erratically or have stopped working.
- ✔ Security system malfunctions, including no-start or no-crank conditions.
- ✔ A variety of communication codes or seemingly unrelated DTCs stored in the vehicle’s memory.
Installation is straightforward for the seasoned DIYer or any professional technician. The BCM is typically located under the driver’s side dash, near the steering column. Simply disconnect the battery, un-plug the connectors from the old module, remove it, and install the new one. While most installations are plug-and-play, some vehicles may require a ‘Setup SDM Primary Key in BCM’ procedure with a professional scan tool if the airbag light remains on. There is no core charge, so you can keep your old part without any hassle.

Frequently Asked Questions
What does a Body Control Module do on my 2002-2006 Avalanche 2500?
The BCM acts as the brain for your truck’s body electronics. It controls non-engine related functions like your power windows, locks, interior and exterior lighting, wipers, security system, and HVAC fan speeds.
Is this BCM ready to install out of the box?
Yes! We program the module to your vehicle’s VIN before shipping. This ensures it is ready for a plug-and-play installation, with no need for additional dealership programming.
Where is the BCM located on my truck?
On most compatible GM trucks and SUVs like the Avalanche, Silverado, and Sierra, the BCM is located under the driver’s side of the dashboard, typically near the steering column. On Express and Savana vans, it is often found in the center dash area.
What if my airbag light is on after I install the new BCM?
In some cases, the new BCM needs to be synced with the airbag system’s Sensing and Diagnostic Module (SDM). This requires a professional scan tool to perform the ‘Setup SDM Primary Key in BCM’ procedure to clear the light.
Do I need to send my old part back for a core charge?
No, there is absolutely no core charge for this part. You can keep your old module without any extra fees or hassle.
